体育文化扩散受比邻扩散和等级扩散作用的共同影响。
Sport culture diffusion is influenced by neighborhood diffusion and hierarchical diffusion.
当反应程度达到60%左右后,由于交联程度增加,分子质量迅速增大,分子间扩散较慢,进入反应的第二阶段,主要由扩散作用控制固化速率。
When the curing extent was about 60 percent, the molecular weight raised rapidly and diffusion control was incorporated to describe the cure in the latter stages.
然而在油藏开发实践和理论研究中,大多习惯性地将对常规油藏注气开采中分子扩散作用的认识沿用到裂缝性油藏注气开发中,即认为分子扩散可以忽略。
But in practice or theoretical studies, most people follow a wrong opinion that for a fractured reservoir molecular diffusion is negligible during gas injection as for a non-fractured reservoir.
Remember that these cells are relatively large compared to bacteria and so diffusion doesn't occur very quickly over this length scale.
要知道这些细胞相对细菌而言,还是比较大的,扩散作用在这种尺度上,发生得不是那么快
Diffusion mixes things very well, but as the size gets bigger, diffusion becomes very slow.
扩散作用使物质充分混合,但随着细胞变大后,扩散作用就捉襟见肘了
In general, inside of a cell molecules move by a process called diffusion.
总的来说,细胞内的分子通过扩散作用来移动
